Select by the specific water-circuit use. For ballast water, follow the approved treatment system's chemical requirements.

Environment and objectives

First confirm what is being treated and at which treatment stage.

Shipboard domestic water, seawater cooling, offshore utility water, ballast water and ship sewage.

Operating conditions to check first

Drinking water, cooling water, ballast water and sewage have different requirements. Generic chemicals cannot be freely substituted in ballast-water systems.

Compare candidate treatment approaches

Why each approach is recommended and under which conditions it applies.

01
Disinfection option

Chlorine / chlorine dioxide systems for shipboard water supply

Reason for recommendation
For disinfection within engineered shipboard domestic-water supplies.
Conditions of use
Confirm vessel, flag-state, port and water-supply management requirements.
Documents to verify
Domestic-water use documents; water-circuit diagram; water quality and residuals; equipment maintenance
Discuss this approach
02
Engineered treatment option

Seawater electrochlorination and related cooling-water antifouling options

Reason for recommendation
For seawater cooling-intake and biofouling problems.
Conditions of use
Check seawater composition, materials, discharge and plant design. This does not establish suitability for every marine water use.
Documents to verify
Equipment design; materials/corrosion; residual-oxidant monitoring; discharge requirements
Discuss this approach
03
System-specific support

Active substances and neutralizers specified for an approved BWMS

Reason for recommendation
Match the chemical to the specific ballast-water management system model.
Conditions of use
Approval of an active substance does not approve every device or every supplier's chemical.
Documents to verify
System type approval; applicable active-substance documents; equipment-manufacturer specifications; trading-route requirements
Discuss this approach
04
System-specific support

UV or chemical-disinfection support for ship sewage

Reason for recommendation
Assess within the approval scope of the ship's sewage-treatment plant.
Conditions of use
Meet treatment-plant and discharge requirements. Do not simply apply land-based wastewater parameters.
Documents to verify
Plant approval; effluent standards; chemical compatibility; operational validation
Discuss this approach

This comparison supports initial purchasing screening. It does not replace the specific formulated product label, equipment instructions or site validation, and provides no universal dosage or on-site mixing instructions.
